What mg of Oxycontin is comparable to 30 mg of codeine?

Hydrocodone and Oxycontin contain the same active drug... oxycodone. So 10mg of Hydrocodone and 10 mg of Oxycontin have the same amount of Oxycodone (10 mg) in them. The only difference is that the Hydrocodone contains Tylenol in addition to the Oxycodone. So on the Hydrocodone bottle it might say something like 10/500. So the Hyrocodone in that instance has 10 mg of oxycodone and 500mg of Tylenol.
